PVC bass reflex port extenders.

The current 139 litre volume of the cabinets I’m planning need a two 100mm diameter 24 cm bass reflex ports to tune to my proposed frequency of 33Hz..

G3D9 – LOST EP [MACH010] Released 24:06:2013

Digital music distribution has reached a pretty good state now, with quality FLAC or WAV online versions of most new music releases being available at the same time as the CD, or even sometimes being the only format smaller releases are using. Since making all these speakers and amps is mostly for the music we play through it, here are some releases of note.. (though maybe not always flac download releases, or even sticking to electronic music). Called “Do Yourself A Favour” as a tribute to Countdown and Molly Meldrum.

First Up:

New release from G3D9 aka Scott Guyver3 as we knew him in the old Clan Analogue days.
Nice meat and potatoes minimal techno, well fitted to the excellent local Melbourne MACHINE label sound.

Bandcamp page to get at the goodies:

Also available at a bunch of other places, but I prefer Bandcamp for the nice crispy flacs:

Unfortunately I couldnt make it to the launch party, but there is a live set recording available here:
